Let `lim_(xto0) ([x]^(2))/(x^(2))=m,` where `[.]` denotes greatest integer. Then, m equals to

A

`-(1)/(sqrt(2))`

B

`(1)/(sqrt(2))`

C

`sqrt(2)`

D

`-sqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:
B

`([x]^(2))/(x^(2))=[{:(0", ""if "0ltxlt1),((1)/(x^(2))","" if "-1ltxlt0):}impliesl " does not exist"`
`([x]^(2))/(x^(2))=[{:(0", ""if "0ltxlt1),(0","" if "-1ltxlt0):}impliesm" exists and is equal to 0"`
